Whats a Coupe Middy?

 

coupe mid pipe, center section of the exhaust. the 03-04 sedans have a big resonator, 05-06 sedans have smaller resonator, and the 03-07 coupes have very small resonator

 

Ok got it, thanks.

 

very interesting read......glad to see more tuner shops putting there time into our vq's now that they have become somewhat more affordable. i'll be getting tuned on may 8 with CHRIS BLACK from AMS performance......so wen i get all the results together i'll have a post up shortly. im hoping for the best but trying to refrain from picturing a number in my head becuz i dont want to dissapoint myself BTW i have an 03 g35 6mt coupe....so lets see how close i get to 300.

 

Where did you find a 3in throttle body?

 

The best we have done with our 03 6mt track car is 287hp (bolt ons only). That car has seen days of dyno time tweeking it's hp and tq curve. I don't think it has anything left.
BTW, this graph is at only 10% smoothing.

why is the power falling off at 6100 rpm?

 

cause it's not a Rev-up motor.

 

What he said

 

I've seen dynos from N/A non-revup keep making power until 6600 or so and start falling gradually til 7200 rpm.

That is, if the rev limiter was raised :/

 

youd have to have some plenum/intake work done for that to happen, headers would help too. NonRev-DE's with mild bolt on's always fall off around 61 -6200

 

had the stock one bored out and they changed the butterfly housing also to match after

 

how much to have that done and who did the work? Could you tell a difference afterwards?

 

I'm skeptical about all this.. 300whp from only those mods?? How? After all these years of people buying endless mods and doing to most ticky tack things you guys are pulling 300whp that easily? I highly doubt this "CIN" exhaust is making all this power up.

Those aren't even LTH that you're using.

It can't be that powerful of a tune.. I'm saying its the dyno..

I can see a lot of the OG's have not even commented on this as they don't wish to waste their time anymore with this stuff.. Kind of part of the reason I only stick to the lounge because I'm tired of arguements and repeating myself a million times to everyone..

Either way, if this is somehow truly legit I say props to you guys.

 

company is maxbore and owners name is george. they are located in florida. i had my throttle body bored and my cosworth manifold port matched to the throttle body. tb was 125 and manifold was 90, keep in mind i had this done last year and prices can change also thats without shipping.

sadly i did not have enough funds to dyno the pieces by themselves at the time. i've looked around and average gains are 5hp some even none. but i did this because every little help counts wen going the na route especially wen u open up the rest of the bottle necked areas in the stock system the bored throttle bodies potential comes into play. i also got the 3" maf housing from gtm that u should look into ordering before they stop making them

i just recieved these babies today from sg-motorsports
